[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a bearing capacity detection device for a pile-soil composite foundation, including a bottom plate 1, a first connecting block 8, a pressing block 13. The upper surface of the bottom plate 1 is fixedly connected with a support plate 2, the upper surface of the support plate 2 is fixedly connected with a loading platform 3, the upper surface of the bottom plate 1 is fixedly connected with an L-shaped frame 4, the upper surface of the bottom plate 1 is fixedly connected with a first cylinder 5, the output end of the first cylinder 5 is fixedly connected with a bracket 6, the outer wall of the bracket 6 is rotatably connected with a first rotating wheel 7, the outer wall of the first rotating wheel 7 is rotatably connected to the inner wall of the L-shaped frame 4, the inside of the bracket 6 is fixedly connected with a connecting column 9, the inner wall of the first connecting block 8 is slidably connected to the outer wall of the connecting column 9, the outer wall of the first connecting block 8 is fixedly connected with a rectangular plate 10, the outer wall of the rectangular plate 10 is fixedly connected with a second connecting block 11, the outer wall of the second connecting block 11 is rotatably connected with a second rotating wheel 12, the outer wall of the second rotating wheel 12 is rotatably connected to the inner wall of the L-shaped frame 4, the outer wall of the rectangular plate 10 is fixedly connected with an L-shaped support plate 15, both ends of the pressing block 13 are provided with round holes 14, and a limiting component is arranged on the outer wall of the rectangular plate 10 for limiting the pressing block 13; the limiting component includes a limiting baffle 16, and the outer wall of the limiting baffle 16 is fixedly connected to the outer wall of the rectangular plate 10;

[0025] Specifically, the bottom plate 1 can play a role in fixing the L-shaped frame 4 and the first cylinder 5, which can improve the stability of the first cylinder 5 during operation. The first rotating wheel 7 rotatably connected to the outer wall of the bracket 6 and the first connecting block 8 rotatably connected to the outer wall of the second connecting block 11 can improve the smoothness of the bracket 6 when moving upward. The rectangular plate 10 can play a role in fixing the L-shaped support plate 15, and the limiting baffle 16 can play a role in limiting the pressing block 13. After the rectangular plate 10 is turned over, the pressing block 13 can be rolled along the outer wall of the rectangular plate 10 to the upper part of the loading platform 3. During this process, the limiting baffle 16 can prevent the pressing block 13 from shifting when rolling.

[0026] Referring to Figure 2 , a resisting block 17 is fixedly connected to the outer wall of the bracket 6, and the outer wall of the resisting block 17 is attached to the outer wall of the rectangular plate 10;

[0027] Specifically, the resisting block 17 is used to keep the rectangular plate 10 in a vertical state when the pressing block 13 is not lifted.

[0028] Referring to Figure 1 and Figure 4, a second cylinder 18 is fixedly connected to the inner wall of the stage 3. The output end of the second cylinder 18 is fixedly connected to a push rod 19, and a cross bar 25 is fixedly connected to the inner wall of the stage 3; a rectangular block 20 is fixedly connected to the outer wall of the push rod 19. Connecting strips 21 are connected to both the upper surface and the lower surface of the rectangular block 20. A sliding block 22 is rotatably connected to the outer wall of the connecting strip 21; the inner wall of the sliding block 22 is slidably connected to the outer wall of the cross bar 25, and a moving block 23 is fixedly connected to the upper surface of the sliding block 22; a clamping post 24 is fixedly connected to the outer wall of the moving block 23; the outer wall of the clamping post 24 is slidably connected to the inner wall of the circular hole 14.

[0029] Specifically, the stage 3 can fix the second cylinder 18. The second cylinder 18 is used to move the rectangular block 20 through the push rod 19. The connecting strip 21 is used to connect the sliding block 22 and the rectangular block 20. The cross bar 25 is used to guide the movement of the sliding block 22, which can ensure that the sliding block 22 always moves along a straight line when driving the moving block 23. The clamping post 24 is used to slide on the inner wall of the circular hole 14 opened at both ends of the pressing block 13 to fix and limit the pressing block 13, which can prevent the pressing block 13 from displacing above the stage 3.

[0030] Working principle: When the device needs to be used, first place the pressing block 13 above the L-shaped support plate 15, and then start the first cylinder 5. The start of the first cylinder 5 causes the bracket 6 to move upward. The upward movement of the bracket 6 drives the first rotating wheel 7 and the second rotating wheel 12 to rotate within the inner wall of the L-shaped frame 4. At the same time, the connecting column 9 and the first connecting block 8 also drive the rectangular plate 10 to move upward. When the second rotating wheel 12 rotates past the corner of the inner wall of the L-shaped frame 4, the second connecting block 11 will flip clockwise, and then drive the rectangular plate 10 to flip clockwise through the second connecting block 11. During this process, the inner wall of the first connecting block 8 will slide on the outer wall of the connecting column 9 and flip accordingly. When the rectangular plate 10 flips to the horizontal position, roll the pressing block 13 along the outer wall of the rectangular plate 10 until it rolls above the carrier 3, completing the placement of the pressing block 13. Thus, the placement of the pressing block 13 is time-saving and labor-saving, the lifting is stable, and the operation safety is high, which can reduce the safety hazards during operation. When the pressing block 13 is lifted above the carrier 3, roll the pressing block 13 to the position where the clamping post 24 is aligned with the round hole 14, and then start the second cylinder 18. The start of the second cylinder 18 causes the push rod 19 to drive the rectangular block 20 to move towards the direction of the second cylinder 18. As a result, the connecting bar 21 rotates on the upper surfaces of the rectangular block 20 and the sliding block 22 while pulling the sliding block 22 to slide inward within the inner wall of the cross bar 25. Thus, the sliding block 22 drives the moving block 23 to move inward, and the moving block 23 moving inward drives the clamping post 24 to slide within the round holes 14 opened at both ends of the pressing block 13, thereby completing the fixation of the pressing block 13, which can ensure that the position and angle of the pressing block 13 on the testing device will not accidentally move or deviate, improving the accuracy and precision of the test, enhancing the operation safety, and reducing the safety hazards during the operation process.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
